Ask Tim Grey - Digital Photography Podcast

Tim Grey's answers and commentary for photographers...

Tim and Renee chat about a "quadcopter" drone crashing onto the lawn at the White House in Washington, D.C., and how that might impact photographers who want to use drones for aerial photography. They then address questions from photographers about calibrating digital projectors, the impact of ISO on exposure and image quality, file size and resolution, extending canvas size in Photoshop, and the resolution to use for digital sharing.
